Einstein’s general theory of relativity (GR), from 1915, remains the most successful description of gravitation. From the 1919 solar eclipse to the observation of gravitational waves, the theory has passed many crucial experimental tests. However, the evolving concepts of dark matter and...Read more about Observation of the effect of gravity on the motion of antimatter
"If you can't contain it, you can't study it. That's the case with antimatter, an elusive substance that may hold secrets to matter, time and the universe. So far experiments, including work at CERN in Switzerland, had failed to confine antihydrogen. In this landmark 2010 paper, Gorm Andresen and...Read more about Trapped Antihydrogen Selected as one of 40 Research Milestones
Alpha's latest breakthrough, the first observation of the 1S-2S transition in trapped antihydrogen has been published in Nature and is the first time a spectral line has been observed in antihydrogen. This builds on years of work, developing techniques to manipulate super-cold antiprotons and...Read more about Observation Of The 1S-2S Transition In Trapped Antihydrogen Published In Nature
Abstract: The ALPHA experiment performs both spectroscopic and gravitational measurements on antihydrogen. Apparatus can trap only about one atom at a time! All proposed measurements are difficult to perform on a single (anti-) atom. Proposal: Increase the number of antihydrogen atoms available to...Read more about Novel Microwave Cavity for Resonant Cooling of a Lepton Plasma
Abstract: Generating cold (<50 K) single component electron plasmas is of critical importance to many experiments. Examples include optimizing recombination rates for antihydrogen or Rydberg atom production and producing mono-energetic beams. Replacing a section of a Penning-Malmberg trap with a...Read more about Cyclotron-Cavity Mode Resonant Cooling in Single Component Electron Plasmas
